SrCu_2(BO_3)_2 - a Two Dimensional Spin Liquid
Christian Knetter, Alexander Buehler, Erwin Mueller-Hartmann +1
We study an extended Shastry-Sutherland model for SrCu_2(BO_3)_2 and analyze the low lying parts of the energy spectrum by means of a perturbative unitary transformation based on f…

Mediation of Long Range Charge Transfer by Kondo Bound States
R. G. Endres, D. L. Cox, R. R. P. Singh +1
We present a theory of non-equilibrium long range charge transfer between donor and acceptor centers in a model polymer mediated by magnetic exciton (Kondo) bound states. Our model…
